Multifocal tuberculosis in children: A case of spinal tuberculosis.

Multifocal tuberculosis (TB) accounts for up to one-third of all cases of TB and children are at higher risk for extrapulmonary TB than adults. Spinal TB is the regular form of skeletal TB. Spondylodiscitis TB represents 47%-94% of spinal TB. Cervical localization is rare but remains dangerous because of diagnostic difficulties and severe complications. We report a case of a 10-year-old Moroccan girl, bacille Calmette-Guerin vaccinated, with no medical history or trauma, parents and siblings are healthy and no contact with TB. The patient was complaining of neck pain, asthenia, and loss of weight for 1 year. During this period, she had been treated with analgesics and anti-inflammatory drugs, with no clinical evolution. The parents consulted the pediatric emergency room when they noticed a tumefaction in the middle thoracic region. Physical examination found a pectus carinatum deformity, palpable axillary, and submandibular lymph node, and a fixed palpable median thoracic mass fistulized to the skin. The GeneXpert MTB/RIF and QuantiFERON-TB Gold assay were positive. Chest computed tomography showed cervicodorsal spondylodiscitis staged at C5-D10, with abscessed perivertebral and peristernal collections, with epidural extension at C5-C6 and pleural level. The presence of an axillary lymph node with necrotic center. The skin biopsy showed a morphological appearance of epithelial and gigantocellular granulomatous inflammation. The patient had pharmacological treatment anti-TB drug with fixed-dose combination regimen and supportive therapy for pain management.
